BAG-FASTENER.

SPECIFICATION forming part of Letters Patent No. 281,663, dated July 24, 1883.

' Application filed April 28,1883. (No model.)

, rubber.

The object of the improvement is to furnish a simple and reliable fastener, readily applied and effective when in place. These objects I attain by the use of the article shown in the accompanying drawings, which form a part of this specification, and in which similar parts are correspondingly marked.

Figure 1 is an elevation of the complete fastener. Fig. 2 is a section on the same plane. Fig. 3 shows the application of the fastener to a bag. Fig. 4 is a half-elevation and plan of the locking portion of the fastener. Fig. 5 is a half-elevation and plan of the spring locking-catch.

A represents the neck of the bag; B, the locking portion of the fastener, having ahingejoint, B, a thumb-piece, B and a locking-slot, B Thespring locking portion or catchOhas a bifurcated joint, 0, a barbed head, 0 and a catch, 0*. The fastener is secured to the bag by a strap, chain, or leather thong passed through the perforation D in the end of the hinge-j oint B of the portion B, and sewed, riveted, ortied thereto, as found most desirable.

The fasteners may be stamped out of any suitable metal, or may be cast from the same; and if made from celluloid or equivalent material in quantities, they would be inexpensive.

To use this fastener,the neck of the bag is gathered, as is usual for tying, and the fastener, opened, as shown in dotted lines in Fig. 2, is placed against the crimped portion of the bagneck. The piece 0 is then brought over for its end 0 to enter theslot B in B, and, being squeezed or compressed, (the head Otbeing pressed under theupper edge of the slot B the elasticity of the ring 0 permitting it,)

passes into and through the same until the catch arrives outside of the head B when,

being relieved from compression, the ring 0 springs upward and locks the fastener.

To open the bag, the catch 0 is depressed, and at the-same time pushed through the slot Biwhen the ring is opened, as before, the bag released, and its contents exposed.

The fasteners will be made in their internal diameter of suitable size for-the bags to which they are to be applied. The elasticity of the fastener, however, permits considerable variation in the'thickness of the material before it would becomeinoperative; and even if atrifie loose on a bag the end seam or fell prevents the-slipping of thefastener, and the contents of the bag are securely held.

I am aware that I am not the first to produce a bag fastener in two parts centrally hinged, (see Patent No. 96,229, October 26, 1869, to O. A. Haring,) and do not therefore broadly claim the same; but I believe my fastener to be an advance in the art, more easily manufactured, more reliable, and better adapted for the purposedescribe'd. 7

Having given detailed views of my invention and explained its construction and use, I desire to secure by Letters Patent-the following claims:

1. A bag-fastener of suitable material, constructed of two separate pieces hinged and locked separably together at diametrically-opposite points, as and for the purpose set forth.
